How To Fix My Bent Brake Lever?

Change it. Bending it back will likely break it, it’s weakened anyway. It shouldn’t be hard to pop out the pin on those.

In all likelihood that lever will snap if you bend it back, even if it doesn’t, it’ll likely be much weaker than it should be. A lever snapping when you pull it could lead to a serious injury, or worse, I wouldn’t risk it.

You can call the dealer or google your make and model of lever and buy a new blade for approx. $10-12

EDIT: you need a Tektro HD-MD280 lever blade

My kid had a crash and did something very similar. His brake levers are Tektro banded as well (different model number). What I did was just google “replacement lever + model number”. https://trpcycling.com/products/hd-m280-lever-blade. I then found a youtube video on how to remove the old one and install the new. All I needed was a couple of allen keys. However, in your case it looks like you could just buy the whole assemble from the MFR https://trpcycling.com/products/hd-m280. That is a bit more involved. After removing the brake line from the assembly, you would need to cut the line just above the barb and install and install a new barb and olive to the line. Then reattach the line to the assembly. That does require some specific tools (hose cutter and barb tool + Tektro specific olive and barb). If you aren’t comfortable doing that kind of replacement or don’t have the specific tools you could take it to your LBS to have them do the work.

if you want to try bending it, I suggest spreading the back of the u in the lever (backside) using a flathead turn the screwdriver to spread out the Ushape in the lever vs trying to bend straight; I have successfully rehabed a set of Sram levers that got hit hard.

Replace it.

These levers aren’t typically made from a metal that can stand up to bending back and forth without becoming exceptionally weak. The last thing you want is to go to grab a fistfull of brake on a fast descent and have the lever come apart in your hand.
